With this relatively new chipset, it is also crappy:
VGA compatible controller: Intel Corporation 82G33/G31 Express 
Integrated Graphics Controller (rev 02)

The regressions started to appear in F9/KDE4. Until F8, it was perfect 
:/ Currently, garbage often appear on screen at random places if desktop 
effects are enabled and open gl applications behave strangely when other 
windows are opened over or under them.
I still didn't move on from F8 on my laptop because of this.
